摘要(英):
A method for producing an epitaxial wafer includes a step of growing an epitaxial layer structure on a III-V semiconductor substrate, the epitaxial layer structure including a III-V semiconductor multiple-quantum well and a III-V semiconductor surface layer, wherein the step of growing the epitaxial layer structure on the substrate is performed such that a lattice mismatch [Delta][omega] of the multiple-quantum well with respect to the substrate satisfies a range of -0.13%<=[Delta][omega]<0% or 0%<[Delta][omega]<=+0.13%, the range having a center displaced from zero, and an X-ray rocking curve in a zero-order diffraction peak derived from the multiple-quantum well has a full width at half maximum (FWHM) of 30 seconds or less.
